Question

The ultrasonic transducer used in a medical ultrasound imaging device is a very thin disk (m = 0.10 g) driven back and forth in SHM at 1.0 MHz by an electromagnetic coil.

a. The maximum restoring force that can be applied to the disk without breaking it is 50,000 N. What is the maximum oscillation amplitude that won't rupture the disk?

b. What is the disk's maximum speed at this amplitude?
